[dpdk-dev] [PATCH v2] net/ring: advertise multi segment TX and scatter RX.

Even though ring interfaces don't support any other TX/RX offloads they
do support sending multi segment packets and this should be advertised
in order to not break applications that use ring interfaces.

Also advertise scatter RX support.
